This document discusses a day night antiglare wind screen for vehicles. Such a wind screen aims to provide a safer driving experience by reducing glare from sunlight or high beams. It does this through an optical coating that allows the windscreen to change tint based on light conditions, remaining clear at night but darkening in intense sunlight up to 70% light transmittance. This helps prevent accidents caused by temporary blindness from glare and allows for safer driving in various light conditions. The document outlines the problems of glare and analyzes existing solutions as well as proposing the day night antiglare windscreen as an improved option.
